This Galápagos finch is confined to the island of Genovesa. It has a fairly large bill that appears slightly elongated. The only other finch on Genovesa with a similarly-sized bill is Large Ground-Finch. Compared to that species, Genovesa Cactus-Finch has a smaller, less rounded bill that is noticeably longer than it is deep. Bill is pure black on breeding male, and marked with yellow or orange on female and non-breeding male. Male’s plumage is sooty-black; female is brown with paler underparts that are blotched with gray. Common in arid areas near the coast, and often seen feeding on prickly pear flowers.
